6 I am amazed that you are so quickly forsaking the one who called you by [the] grace [of Christ] for a different gospel 7 (not that there is another). But there are some who are disturbing you and wish to pervert the gospel of Christ. 8 But even if we or an angel from heaven should preach [to you] a gospel other than the one that we preached to you, let that one be accursed! 9 As we have said before, and now I say again, if anyone preaches to you a gospel other than the one that you received, let that one be accursed! 10 Am I now currying favor with human beings or God? Or am I seeking to please people? If I were still trying to please people, I would not be a slave of Christ. - Galatians 1:6-10
Notice that Paul says TWICE that if anyone comes along and preaches a gospel other than the gospel of Christ, let that one be accursed. Re: verse 10, Osteen is seeking to please people, not God.
If you are buying into the LIE that is the 'Prosperity Gospel' - the FALSE GOSPEL of Joel Osteen - I urge you to watch these two videos. There is a plethora of information showing CLEARLY the false teachings of Osteen, these are pretty thorough. The first one is just over an hour but really thorough, and the second one is about 20 minutes but does not go into as much detail.
Beware of the False Gospel of Joel Osteen
What's the problem with Joel Osteen?
There's a great deal more to warn about Osteen, Paula White, Benny Hinn, TD Jakes, Victoria Osteen, Joseph Prince, Joyce Meyer, and others. I'll post videos from time-to-time. Yes, they do say some uplifting things... but they are NOT representing the Gospel of Jesus Christ. Period.
